Elasticsearch7.1 REST操作。

#### 本博客近期教程笔记都基于elasticsearch7编写 ####

1.  创建空索引（put方式）  
      
    ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwMzc0NjA0_size_16_color_FFFFFF_t_70][]  
    
2.  查看索引信息（demo/\_mapping?pretty GET）  
    可以看到，mapping为空。  
      
    ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwMzc0NjA0_size_16_color_FFFFFF_t_70 1][]  
    
3.  构建索引数据结构
    
        [POST]
        
        demo/_mapping?pretty
        
        {
            "properties":{
                "title":{
                    "type":"text",
                    "analyzer":"ik_max_word"
                },
                "content":{
                    "type":"text",
                    "analyzer":"ik_max_word"
                }
            }
        }
    
    展示图![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwMzc0NjA0_size_16_color_FFFFFF_t_70 2][]
4.  查看mapping \[ demo/\_mapping?pretty \] GET  
      
    ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwMzc0NjA0_size_16_color_FFFFFF_t_70 3][]  
    
5.  搜索\-（在构建索引时，指定了插入和搜索都用ik分词，这里只设定了from和size字段）  
    
    
        【POST】
        
        demo/_search
        
        {
            "query":{
                "term":{
                    "name":"美国"
                }
            },
            "from":"0",
            "size":"20"
        }
    
    展示图  
    ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwMzc0NjA0_size_16_color_FFFFFF_t_70 4][]
